Im looking for something that will cover probably a 3x4 area. I have never used LEDS. I have grown from start to finish with HOT5s and i have used HPS. The HOT5s were a 8 tube 4ft system that put out 40,000 lumens and i got some really nice buds. Of course HPS does a better job in flower then the HOT5s but i couldn't deal with the heat in Texas with the HPS. So i am really thinking when i get around to building another grow room that i want to use LEDS and your grow looks great with those LEDS.
